The AquaJelly is has been designed to autonomously emulate swarming behavior of wild jellyfish (Image: Festo)

The AirJelly's center of mass displaced in the direction of a pendulumÃ¢â‚¬â„¢s motion which causes the jellyfish to move in the same direction (Image: Festo)

The AirJelly is powered by batteries transmitting force to a bevel gear wheel which in turn powers eight spur gears in sequence, eight shafts activating eight cranks, which each move one of the eight tentacles (Image: Festo)

The AirJelly is propelled by a peristaltic forward motion; the first indoor flight object with peristaltic drive! (Image: Festo)

Festo, the automation company that designed the bionic penguin and its robotic stablemates – AirRay, AquaRay, AirJelly and AquaJelly – has found another natural model in its latest application of biomimicry – the elephant's trunk.
